However, fellow producer Andrew Kreisberg told The Hollywood Reporter: "I'm not entirely sure you'll be seeing characters like Superman, Batman, Green Lantern and Wonder Woman because they're much more fantastical and right now we're focusing on Oliver Queen as being the only hero."

He added that the series is more likely to focus on DC's "lesser-known characters" in future episodes.

"We're looking forward to bringing on other DC Comics characters and characters that people have never really seen before," he explained. "That's what's been fun for us; Superman will always get his due [on TV and film]."
